Abstract

Tachinidae is one of the largest families of Diptera in number of species, habits and forms. Besides, all species are parasitoids of other arthropods. Because of this high diversity and the lack of adequate taxonomic studies, Tachinidae classification is still uncertain and doubtful, especially in the Neotropical Region. Currently, Tachinidae is classified into four subfamilies: Phasiinae, Dexiinae, Exoristinae and Tachininae, the latter including the tribe Ormiini. Ormiini flies occur throughout the world and are mainly characterized by locating their hosts (Orthoptera, Ensifera) phonotactically. This is possible because they have a prosternum modified into an acoustic membrane. The genus Ormiophasia Townsend, 1919 includes nine species and is the only ormiini genus endemic of the Neotropical Region. Therefore, this project aims to contribute to the knowledge and classification of Tachinidae, with the taxonomic revision and morphological cladistic analysis of Ormiophasia. In the revision, the valid species will be redescribed, and the new species described, as well as an identification key to species will be provided. Material from national and international museum collections will be requested and studied. For the cladistic analysis, the characters will initially be treated with equal weights, non polarized, and, in case of multistate characters, unordered. The data matrix will be prepared using the Winclada software and the analysis will be carried out with the TNT software. Branch support will be verified by Bremer index and by bootstrap frequencies. Implied weighting will be applied after the former analysis to better understand how the characters fit the trees.
